NOTE 1: The signal applied to the USART receive signal/terminal (URXD) should meet the timing requirements of t(τ) to ensure that the URXS
flip-flop is set. The URXS flip-flop is set with negative pulses meeting the minimum-timing condition of t(τ). The operating conditions to
set the flag must be met independently from this timing constraint. The deglitch circuitry is active only on negative transitions on the
URXD line.
